Selvam,
You can use EvaluateJsonPath to extract the particular JSON value into an
attribute
and then use RouteOnAttribute to make sure that the field exists (and is valid
if necessary).
For example, for EvalualteJsonPath you might use something like:
name: $.person.name
And then in RouteOnAttribute, you could use:
missing.name: ${name:isEmpty()}
If you have multiple fields to check on RouteOnAttribute, you could create a
separate Relationship
for each rule by setting the "Routing Strategy" property to "Route to Property
Name" or you could
set the Routing Strategy to "Route to 'matched' if any matches" and then
the 'unmatched' relationship would indicate that the JSON is valid.
Thanks
